Patent number: 11924444Abstract: Method and apparatus for constrained de-blocking filter are disclosed. One method receives input data related to a current block in a current picture at a video encoder side or a video bitstream corresponding to compressed data including the current block in the current picture at a video decoder side, and determines a first boundary associated with the current block, wherein the first boundary corresponds to one vertical boundary or one horizontal boundary of the current block. The method then applies de-blocking process to a reconstructed current block corresponding to the current block to result in a filtered-reconstructed current block, using a plurality of first reference samples at a same side of the first boundary, and replaces a first set of the first reference samples by one or more padding values. The method then generates a filtered decoded picture including the filtered-reconstructed current block.Type: GrantFiled: April 11, 2022Date of Patent: March 5, 2024Assignee: HFI INNOVATION INC.Inventors: Chia-Ming Tsai, Chih-Wei Hsu, Ching-Yeh Chen, Tzu-Der Chuang, Yu-Wen Huang

Patent number: 11909965Abstract: Methods and apparatus for Adaptive Loop Filter (ALF) processing of reconstructed video are disclosed. According to one implementation, a method receives reconstructed pixels of a current block and determines one or more clipping values for the ALF processing, wherein a target clipping value is always signaled at an encoder side or parsed at a decoder side even if the target clipping value is zero. The method then derives a current ALF output for the current block, wherein the current ALF output has a weighted sum of clipped differences and each of the original differences is calculated between a first reconstructed pixel at a non-center filter location and a center reconstructed pixel at a center filter location, and each of the original differences is clipped according to a corresponding clipping value to form one clipped difference. The method then provides filtered-reconstructed pixels.Type: GrantFiled: August 12, 2022Date of Patent: February 20, 2024Assignee: HFI INNOVATION INC.Inventors: Chen-Yen Lai, Ching-Yeh Chen, Tzu-Der Chuang, Yu-Wen Huang

Publication number: 20230369501Abstract: Techniques are provided herein for forming transistor devices with reduced parasitic capacitance, such as transistors used in a memory structure. In an example, a given memory structure includes memory cells, with a given memory cell having an access device and a storage device. The access device may include, for example, a thin film transistor (TFT), and the storage device may include a capacitor. Any of the given TFTs may include a dielectric liner extending along sidewalls of the TFT. The TFT includes a recess (e.g., a dimple) that extends laterally inwards toward a midpoint of a semiconductor region of the TFT. The dielectric liner thus also pinches or otherwise extends inward. This pinched-in dielectric liner may reduce parasitic capacitance between the contacts of the TFT and the gate electrode of the TFT. The pinched-in dielectric liner may also protect the contacts from forming too deep into the semiconductor region.Type: ApplicationFiled: May 12, 2022Publication date: November 16, 2023Applicant: Intel CorporationInventors: Cheng Tan, Yu-Wen Huang, Hui-Min Chuang, Xiaojun Weng, Nikhil J.

Patent number: 11805245Abstract: For each prediction candidate of a set of one or more prediction candidates of the current block, a video coder computes a matching cost between a set of reference pixels of the prediction candidate in a reference picture and a set of neighboring pixels of a current block in a current picture. The video coder identifies a subset of the reference pictures as major reference pictures based on a distribution of the prediction candidates among the reference pictures of the current picture. A bounding block is defined for each major reference picture, the bounding block encompassing at least portions of multiple sets of reference pixels for multiple prediction candidates. The video coder assigns an index to each prediction candidate based on the computed matching cost of the set of prediction candidates. A selection of a prediction candidate is signaled by using the assigned index of the selected prediction candidate.Type: GrantFiled: July 26, 2022Date of Patent: October 31, 2023Inventors: Chih-Yao Chiu, Chun-Chia Chen, Chih-Wei Hsu, Ching-Yeh Chen, Tzu-Der Chuang, Yu-Wen Huang
